How a booking works

Booked. Diagnosed. Sorted.

Four steps from "my car's playing up" to "drive away sorted".

  1. 01

    Book online

    Live availability. Pick a slot that works. No phone tag.

  2. 02

    Drop the car

    Off-street parking at Secker Road. Walk to the cafés while we work.

  3. 03

    We diagnose

    Scan tools first, guesswork never. Quote before any repair starts.

  4. 04

    Drive away sorted

    Repaired, tested, explained. Receipts and warranty in writing.

What we do

Three core services. One promise: diagnose first, quote second.

01

Auto Electrical

From a flat battery on a Monday morning to a full accessory fit-out on a 4WD. We test every connection, isolate the fault and explain what we found before we touch the wiring.

  • Battery, alternator and starter testing
  • Wiring diagnosis and repair
  • Light bars, dual battery, UHF, tow wiring
  • Trailer and caravan electrical
  • Reverse cameras, dash cams and parking sensors
  • Anderson plugs and 12V outlets for camping setups

Most jobs done same-day if you book the right slot. Quoted on inspection, no surprise add-ons.

02

Air Conditioning

Dead aircon before summer is a known regret. We re-gas, leak-test and rebuild systems on anything from daily commuters to old 4WDs. Refrigerant work is licensed and logged properly, every job.

  • Re-gas and pressure test (R134a and R1234yf)
  • Leak detection with UV dye and electronic sniffer
  • Compressor diagnosis and replacement
  • Condenser, evaporator and TX valve repairs
  • Full system rebuild on older 4WDs and classics
  • Cabin filter replacement included on full services

Quoted in writing after the pressure test, before any refrigerant goes in. Logged so the work stays compliant.

03

Advanced Diagnostics

Manufacturer-grade scan tools, CAN bus testers and an oscilloscope. We find what the cheap reader misses, then walk you through what the data actually means.

  • ECU fault code scan, log and clear
  • Module communication tests across CAN, LIN and FlexRay
  • Live data analysis under road-test conditions
  • Intermittent fault tracing with data logging
  • Pre-purchase electrical inspections
  • Written quote before any repair work

Diagnostic appointment booked online. Written quote, credited toward the repair if you go ahead with us.

What customers say

Five-star service. Twenty-four reviews.

  1. “This is the guy that shows how customer service could be done at the service centre of where you bought your new car. Craig = legend.”

    Tim Garrett Local Guide · Google review
  2. “Craig is an excellent car electrician. My car had ongoing daylight running light issues, and I was having to replace the bulb almost every month. Craig fixed the problem using his expertise. He is honest, reliable, respectful and trustworthy.”

    Parvesh Chaudhary Local Guide · Google review
  3. “Got the Audi S5 aircon re-gased. Craig was terrific: very friendly, quick and helpful. Excellent service and great price. Highly recommended!”

    Matthew Randell Verified Google review
  4. “Had Craig organise and fit a lightbar to our new car. He gave a few suggestions and we went with the Hella black magic. His workmanship was second to none, the wiring all neatly done and hidden where possible, the lightbar perfectly centred. Can't recommend enough!”

    Josh Keelan Verified Google review
  5. “Excellent service from Tarc-Air today. I dropped in with the intention of booking my vehicle in for analysis but Craig kindly took a look at the problem of my sidelights interfering with my indicators and found a faulty trailer socket which he then replaced. I was able to drive away with the problem solved!”

    David Fletcher Verified Google review

    Karen Leane Verified Google review

    Andrew Stagg Verified Google review

Common questions

Stuff people ask before booking.

How much will it cost?

We diagnose before we quote. You get a fixed price for the work in writing before anything starts. No "we found another problem" surprises mid-job.

How long does an aircon re-gas take?

About an hour for a standard re-gas with no leaks. If we find a leak, we'll quote the repair before going further. Walk to the Mount Barker cafés while you wait.

Do you fit my own parts?

For 4WD accessories, usually yes. For replacement electrical components (alternators, starters), we prefer to supply so we can stand behind the warranty. Ask when you book.

Are you qualified to handle refrigerant?

Yes. We're authorised by the Australian Refrigeration Council. That's the legal qualification to handle automotive refrigerants in Australia. Look for our ARC licence card in the trust strip and footer of the site.

What payment do you accept?

Card and bank transfer. Receipts emailed automatically. Workshop Software handles all the back-end so the paperwork is clean.

Do you offer a warranty?

Yes, on parts we supply and workmanship. Specifics depend on the part and manufacturer, written on every invoice. Ask if you want detail on a particular job.
